Hai everyone

I’ve made shopping list for Beagleboard-xm(296-25798-ND) & its peripherals. Can someone please check whether these item will match with board(xM) specifications. am selected all the parts from Digi-Key itself , Parts no are given below. Also please help me to find some missing parts.

  1. Power supply : T377-P5P-ND

    (is this suitable ? as per the BB-xM Reference Manual Supply maximum is 3A (pag no :164). but this one having 3.2A , also what about connector size?)

  2. HDMI - DVI-D Cable : WM19082-ND or WM19090-ND

  3. S-Video Cable : AE10074-ND

  4. To connect to USB OTG : 10-00003-ND

  5. Serial cable (DB9 Straight through Male to Female) : ???

  6. Power connector (is this really needed?) : CP-2185-ND

   1. Power supply : T377-P5P-ND
      <EMS050320-P5P-SZ CUI Inc. | Power Supplies - External/Internal (Off-Board) | DigiKey;

      (is this suitable ? as per the BB-xM Reference Manual
      <http://beagle.s3.amazonaws.com/design/xM-A/BB_xM_SRM_A2_01.pdf&gt;
      Supply maximum is 3A (pag no :164). but this one having 3.2A ,
      also what about connector size?)

3.2A is OK, about connector size, what does the SRM say?

   2. HDMI - DVI-D Cable : WM19082-ND
      <http://search.digikey.com/scripts/DkSearch/dksus.dll?WT.z_header=search_go&lang=en&site=us&keywords=WM19082-ND&x=0&y=0&gt;
      or WM19090-ND
      <http://search.digikey.com/scripts/DkSearch/dksus.dll?WT.z_header=search_go&lang=en&site=us&keywords=WM19090-ND&x=0&y=0&gt;

   3. S-Video Cable : AE10074-ND

most people will want DVI only I guess...

   4. To connect to USB OTG : 10-00003-ND
      <http://search.digikey.com/scripts/DkSearch/dksus.dll?WT.z_header=search_go&lang=en&site=us&keywords=10-00003-ND&x=0&y=0&gt;

   5. Serial cable (DB9 Straight through Male to Female) : ???

or a usb2serial, most PC come without a serial port these days...

   6. Power connector (is this really needed?) : CP-2185-ND
      <http://search.digikey.com/scripts/DkSearch/dksus.dll?WT.z_header=search_go&lang=en&site=us&keywords=CP-2185-ND&x=0&y=0&gt;

why? the above power supply has a connector already...

3

what about tochscreen display?
which will be best suitable?

4

3.2A is OK, about connector size, what does the SRM say?

SRM saying that "supply must have a 2.1mm center hot connector with a
5.5mm outside diameter"

> 5. Serial cable (DB9 Straight through Male to Female) : ???

Any way can you please help me to finding a serial cable (DB9 Straight
through Male to Female) also a serial to USB too..

In case ....

Is there any 'Touch screen with adapter' available in market which can
be hot plugged to BB-xM .Or any Open-source hardware design for the
Touch screen interfacing.

6

no touchscreen or LCD support are provided. You will have to solve all these questions by yourself, using CAD and soldering station :slight_smile:

Thanks . What about any Open Hardware Designs? if there is any such
Design available ? It will be really good, because these days lot of
people working on that.

Special Computing has various Expansion boards for Beagleboard that will be added soon.

One problem I can see with expansion cards for the xM is that current
BeagleBoard expansion cards appear to have a female header and expect
you to have soldered pins to the Beagle, but the xM has a female
socket too, so you'll need something to join female to female headers.

10

That is correct in some cases. The Zippy folks chose not to follow the plan and switched the genders on their board as the Rev C boards were not populated with connectors. Having bare pins on the bottom of every board with the majority of them having no expansion board seemed a little bit of an issue for the -xM board in my opinion, hence the sockets were used. If you do buy a Zippy board you can always just use the header they provide to connect the two sockets.

This seems like a good thing to add to the website. Just today I was
trying to track down what peripherals were needed for the Xm.
  With inline edits in this thread it is hard to determine what the
final list is.

What design do you need? How to connect LCD display to BB? Take a look at OMAP3EVM from Mistral, there you can find a translator part. Take a look at BB schematic and there is there the connector part between a CPU and external voltage translator

I think, that Keith's design[1] is not "open", at least there's no license,
but it seems quite complete and maybe it would work.

I officially ordered my own xm. Now I'll just heave myself on the hammock and snooze, sort of, till it arrives in a few weeks.

I guess I'm looking for xm accessories, too.
